Title: Optical wave guide and manufacture thereof
Inventor: UNO TOMOAKI
IPC: H01S5/11
Filed: 1986-12-26
Abstract: PURPOSE:To form an optical waveguide 8 having low loss easily by previously forming a projecting or recessed section to a section, to which the optical waveguide is shaped, on the main surface of a semiconductor substrate, disordering quantum well structure epitaxial crystal-grown on the section and using the disordered quantum well structure as an optical waveguide layer. CONSTITUTION:A diffraction grating 13 at a predetermined period is shaped into a region, in which a laser section is formed, on a substrate. A striped projecting section 22 is shaped in the direction vertical to the diffraction grating 13. A P-waveguide layer 14 and an MQW active layer 15 and the like are epitaxial-grown continuously. A waveguide layer 19 obtained by diffusing Zn to the waveguide layer 14 and a waveguide layer 20 acquired by diffusing Zn to the MQW active layer 15 and disordering Zn and the like are shaped. When currents are flowed toward an electrode 17 from an electrode 10, oscillation is generated in a distributed feedback laser region in the left side section of the figure, and beams are propagated in the left and right direction extending over the MQW active layer 15 and the waveguide layer 14. Beams propagated in the right direction are propagated in the right direction in low loss extending over the waveguide layer 19 and the waveguide layer 20 in a waveguide region in the right side section of the figure. The progressive direction of beams can be controlled along the direction of the projecting section 22 of the substrate in waveguided beams at that time.

Title: Method for forming solder ball in bga-type semiconductor device
Inventor: TANABE SABURO
IPC: H05K3/34
Filed: 1997-10-28
Abstract: PROBLEM TO BE SOLVED: To set solder balls at required positions on a BGA type semiconductor device at high productivity without a single miss, even if small solder balls are set at a large number of positions. SOLUTION: In the method for forming solder ball as electrodes for external connection, on a board for mounting a semiconductor chip, solder ball pieces are punched sequentially from a metal plate 8 for solder by means of a press 9 according to the arrangement of solder balls on the board. A tape 16 applied with an adhesive is then fed sequentially responding to the punching of the press 9, and the punched solder ball pieces are temporarily pasted onto the board. The solder ball pieces pasted to the tape 16 are thereby transferred onto the board, thus forming the solder balls of a BGA-type semiconductor device.

Title: Production of optical disk
Inventor: OTAKI SHINJI
IPC: B29L17/00
Filed: 1989-11-30
Abstract: PURPOSE:To produce a 2P resin film having high quality with simple operations by irradiating at least the outer peripheral positions of the 2P resin film with UV rays throttled to a beam shape and scanning the beam in a circumferential direction, thereby curing the 2P resin film. CONSTITUTION:The UV beam is scanned in the position of the outside diameter Ro and inside irradiater Ri when the positions 6, 7 are irradiated with the UV rays from above a transparent substrate 4 and a stamper 1 is rotated. If, therefore, the uncured 2P resin liquid diffuses and arrives at the scanning position of the UV beam, the liquid cures in this position and does not diffuse any more. The 2P resin is not cured in the part where the resin liquid does not arrive at the position of the outside diameter Ro and, therefore, the liquid diffuses in succession to the position of the outside diameter Ro and is irradiated with the UV beam, by which the resin is cured. As a result, the diffusion of the 2P resin liquid stops finally in the position of the outside diameter Ro over the entire periphery and the outer periphery of the 2P resin film is truly circular. The UV beam is scanned in the inside diameter position Ri on the inner peripheral side as well in exactly the same manner and, therefore, the 2P resin liquid is cured by the UV rays when the liquid arrives at the inside diameter position Ri. The truly circular inside diameter Ri is thus obtd.

Abstract: PURPOSE:To enable the automatic operation of a press by substracting the initial set value by the number of removed works when they are taken place and allowing the corrected set value corresponding to the initial set value by substracting it with the confirmation of the nil of a work of the chuck unit of the final station. CONSTITUTION:A press is stopped because of the signal inputted to a compara tor 4 from a counter 2 being not coincident with the signal inputted from an initial valuer setter 5 when the defective holding of a work is taken place at some station of A-F. At this time the work of defective holding is removed, a corrected set value 1 is inputted to an initial corrector 6 and the correction signal to substract an initial value alpha is inputted to the setter 5 form the correc tor 6 to re-start the press. In case the removed position is reached the final station with the progress of processing, a sensor 1F transmits the signal of defective holding, which is inputted to a reset signal generator 3 as well. The corrector 6 substracts by one the value of the set correction value with the input of the reset signal. Consequently the signal from the setter 6 becomes alphaas well, making the conditions of existing no removed work.
